Description

The utility model relates to the field of mechanical engineering and is intended for installation on an elastic support of mechanisms and machines subject to dynamic stresses, in particular to an intermediate support of a cardan drive, when installing it to vehicle fastening elements.

The invention relates to the field of mechanical engineering, and in particular to a device for supporting a cardan shaft of a vehicle.

A device for supporting a driveshaft comprising a driveshaft and a device for supporting a driveshaft is known, the device comprising an outer sleeve, an elastomer and a bearing, said bearing using an elastomer connected to the outer sleeve, when the elastomer 5 is deformed with respect to the outer sleeve, the movement of the shaft relative to at least along the axis of the bearing (patent No. DE 102007037401, IPC F16C 27/06, publ. 19.02. 2009).

Known cardan drive of land vehicles containing two flange-forks, three or more cardan joints of unequal angular velocities, a mechanism for changing lengths, an intermediate support with a vibration isolator, a vibration isolator of an intermediate support is covered by flanges of the mating sleeve with a sealed bearing and additional dirt deflectors (RF patent No. RU 2335415, IPC B60K 17/22, publ. 10.10.2008).

The closest set of essential features is a cardan drive of a ground vehicle, containing two forks-flanges, which are connected to a length-changing mechanism through three or more cardan joints of unequal angular velocities, an intermediate support with a vibration isolator, a vibration isolator of the intermediate support are covered by flanges of the clip mating with it, in which a closed-type bearing and dirt deflectors are installed (patent No. BY 12083, IPC B60K 17/22, publ. 06.30.2009).

The disadvantages of these designs is the need for additional equipment for mounting and centering the bearing, in addition, these designs are less technological when repairing the driveshaft.

The task was to create the design of the intermediate support, eliminating the need for special equipment used in the assembly of the support, as well as simplifying the repair work.

The technical result of this technical solution is to simplify the installation of the bearing, the mounting of the deflectors, which allow disassembling the intermediate support to replace the bearing without additional equipment, as well as reinstalling it. The technical result is achieved due to the fact that in the intermediate shaft support containing a vibration isolator, covered by the flanges of the bearing mating sleeve, and the deflectors, the holder is made with an inner annular protrusion, and the deflectors are rigidly attached to the surfaces of the shaft and the part mating with it , for example, by welding.

New features are the performance of the cage with an inner annular protrusion, which allows the bearing to be pressed in exactly in the center of the cage until it contacts the protrusion of the cage, rigid connection of the deflectors on one side to the shaft, and on the other hand to the part mating with the shaft, for example, by welding, eliminates the need for more accurate landing surfaces for the installation of deflectors. Thus, the technical result is achieved.

An analysis of the known technical solutions, carried out according to scientific, technical and patent documentation, showed that the set of essential features of the claimed technical solution is unknown from the prior art, therefore, it meets the patentability condition of the utility model “novelty”.

The utility model is illustrated by drawings:

FIG. 1 - intermediate driveshaft shaft with support;

FIG. 2 - clip.

The intermediate support of the driveshaft is used as an element supporting the design and plays an important role in the good technical condition of the car. The main function that the intermediate support of the propeller shaft performs is maintaining the intermediate shaft in a given position. In addition, the cardan drive is attached to the vehicle frame through an intermediate support.

The intermediate support contains a vibration isolator 1, a cage 2, a bearing 3 and a deflector 4.

The vibration isolator 1 is made of elastic material and is covered by collars 5 of the holder 2. The vibration isolator 1 is rigidly fixed by the shoulders 5 of the holder 2, which eliminates the need for additional fastening of the vibration isolator 1. The vibration isolator 1 is designed to damp vibrations that occur on the driveshaft during movement of the transport shaft facilities. The vibration isolator 1 together with the clip 2 is firmly fixed to the vehicle frame with a clamp.

The clip 2 is made with the outer beads 5 and the inner annular protrusion 6, which is located at some distance from the edge of the clip 2.

The rotation of the cardan gear is provided through the bearing 3 of the closed type. The bearing 3 is mounted in a ferrule 2.

To protect the bearing 3 from environmental influences, two deflectors 4 are installed on both sides of the bearing 3. The deflectors 4 are rigidly attached to the shaft and the mating part, for example, a flange, by welding.

When assembling the intermediate support, the vibration isolator 1 is rigidly fixed in the flanges 5 of the cage 2. The bearing 3 is pressed into the cage 2 until it stops against the protrusion 6, which eliminates the use of special equipment for centering the bearing 3. The dirt deflectors 4 are welded to the driveshaft on the one hand and on the other hand - to the flange. When repairing the unit, the flange with the dirt deflector 4 welded to it is removed and the yoke 2 and bearing 3 are removed. No additional equipment is required.

Using all of the above features allows you to get the claimed technical result.

Intermediate shaft support can be made on standard equipment using modern materials and technologies.
